T0 @ZZ whom, t may concern:

Be it known that IHERBERT S. HANsoN, a citizen of the United States,residing at Caledonia, in the county of Boone and State of Illinois,have invented certain new and useful Improvements in Attachments forStraw-Carriers, ofv which the following is a specification.

This invention relates to improvements in straw-carriers` of that classin which the straw is elevated by an endless belt and which forms a partof threshing-machines.

The especial object of my improvements is to provide means whereby thestraw cannot be blown from the carrier or elevator while on its way fromthe machine to the strawstack.

Theinvention which forms the subjectmatter of this application isadapted to be applied to various forms of endless conveyers and maytherefore be used not only in connection with the manipulation of straw,but also for any other material which is being carried from one point toanother over an endless conveyer and which is liable to be scattered bywind.

In the accompanying drawings, which form a part of this application, Ihave shown my invention as applied to a straw-carrier of simpleconstruction and have illustrated the same in detail in the followingviews.

Figure l is a top plan view of a carrier equipped with my improvements.Fig. 2 is a side elevation of the carrier, showing it in elevatedposition; and Fig. 3 is a side elevation showing the carrier in ahorizontal position.

Referring to the detailsv of the drawin s, A represents the side piecesor boards o the carrier, which are of any desired length and suitablyspaced apart to form a chute or guide. between the sides of which thestraw is conveyed. At each end of these side boards is mounted a rollera/ a', and on the-spindle of one of these rollers is fixed asprocketwheel 0,2, which may be driven from any suitable source and isusually driven by a sprocket-chain from the threshing-machine proper.Traveling over the rollers is an endless belt B, made of canvas usuallyand provided with spaced slats b on its outer surface. D represents asection of timber which is connected with or a part of the frame or bodyof the threshing-machine, the latter not being shown.

Connected with the piece D by the hinges d I:are two slats C, whichextend longitudinally of the endless belt and are arranged above thelatter, as clearly shown. If a wide carrier is needed, more slats may beused. Near .the free ends of these slats are secured clevises c',consisting of iron rods bent with their ends inserted in the slats so asto leave a space or slideway between a portion of the c evises and theupper side of the slats C. Slidably arranged in this slideway is atransverse bar E, to the ends of which are secured crank-levers e, uponwhich are adjustably vmounted counterweights e2, the same being heldupon the levers by set-screws e3. The levers are j ournaled in notchescut in the upper edge of the side pieces A and are held in place bystraps a4.

Projecting from the outer face of one of the side boards A is a pin 0,3,so positioned as to check the movement of the vertical portion of one ofthe crank-levers e', and thus limit their movement in one direction whenthe (livarrier is elevated in the position shown in It will beunderstood that the carrier proper is hingedly vconnected with the frameof the threshing-machine in any suitable manner, so that it may beelevated at dierent angles, as required in the practical operation ofthe machine. The slats C are made of light material and are ofsui'licient Width to eectually cover a portion of straw on its way fromthe latter. As the straw passes under the slats C it has a tendency toaccumulate or pile up near the outer end of the carrier, and in order toprevent it from choking at this point I provide the counterweights abovedescribed, whi ch, coupled with the upward pressure from the accumulatedstraw, will permit the slats C to rise at this point, and thus allow thestraw to pass beyond same to the stack. This movement of the slats iscontrolled in part by the position of the counterweights on thecrank-levers and also by the angle at which the carrier is held, as willbe readily understood.

Having thus described my invention, what I claim isl. An attachment forendless-conveyer frames, consisting of slats arranged longitudinally ofsuch frames and hinged at one end, and adjustable means for controllingthe raising of the free ends of said slats relative to theconveyer-frame.

2. An attachment for endless-conveyer frames consisting of slats hingedat one end rooV IIO

and arranged longitudinally of said frame, means for supporting the freeends of said slatsI said means consisting of a bar slidably arranged onsaid slats, and oounterweighted levers connected With said bar andjournaled in said frame.

y 3. An attachment for endless eonveyerframes consisting of slats hingedat one end and arranged longitudinally of said frame, means forsupporting the free ends of said slats, said means consisting of a barslidably arranged on said slats, levers connected with said bar, Weightsadjustably mounted on said levers and means for limiting the movement ofsaid levers in one direction. 15 In testimony Whereot1 I ai'lix mysignature in presence of tWo Witnesses.
